Question Got an error while trying to make player movement in a 2D template

I got an error called "Assets\PlayerMovement.cs(9,37): CS1002: ;expected

can anyone help please?
here is my code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class PlayerMovement : MonoBehaviour
6. {
7.     private float horizontal;
8.     private float speed = 8f;
9.     private float jumpingPower = 16f
10.     private bool isFacingRight = true;
11.  
12.     [SerializeField] private Rigidbody2D rb;
13.     [SerializeField] private Transform groundCheck;
14.     [SerializeField] private LayerMask groundLayer;
15.  
16.     // Update is called once per frame
17.     void Update()
18.     {
19.         horizontal = Input.GetAxisRaw("Horizontal");
20.  
21.         if (Input.GetButtonDown("Jump") && IsGrounded())
22.         {
23.             rb.velocity = new Vector2(rb.velocity.x, jumpingPower);
24.         }
25.  
26.         if (Input.GetButtonUp("Jump") && rb.velocity.y * 0.5f);
27.         {
28.             rb.velocity = new Vector2(rb.velocity.x, rb.velocity.y * 0.5f);
29.         }
30.  
31.         Flip();
32.     }
33.  
34.  
35.     private void FixedUpdate()
36.     {
37.         rb.velocity = new Vector2(horizontal * speed, rb.velocity.y);
38.     }
39.  
40.     private bool IsGrounded()
41.     {
42.         return Physhics2D.OverlapCircle(groundCheck.position, 0.2f, groundLayer);
43.     }
44.  
45.     private void Flip()
46.     {
47.         if (isFacingRight && horizontal < 0f || !isFacingRight && horizontal > 0f)
48.         {
49.             isFacingRight = !isFacingRight;
50.             Vector3 localScale = transform.localScale;
51.             localScale.x *= -1f;
52.             transform.localScale = localScale;
53.         }
54.     }
55. }
56.  

 

Thanks so much! I didnt know what the numbers meant
